INFLATED ELASTIC BODY WITHIN AN- OTHER INFLATED ELASTIC BODY 2 Claims.

My present invention relates to an improved dual wall inflatable jet propelled toy and more particularly to the structure of the toy which is so designed as to permit the pre-inflation of a simulated craft such as a dirigible, airplane, land vehicle, or water vehicle, and the subsequent inflation of a body within the pre-inflated structure so that the natural exhaust of the inflated body will eflect a jet propulsion of the structure until the inflated body is deflated whereupon the pre-inflated structure will continue in its directed course.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claims.

In the drawings:

Figure 1 is a side elevational view of the toy of my invention partially in section to show the interior thereof.

Figure 2 is an end, rear, elevational view.

Figure 3 is a longitudinal sectional view of the toy showing the inflatable body inflated within the pre-inflated structure.

Figure 4 is a similar view with the inflated body deflated.

Figure 5 is a top plan view partially in section of the structure as embodied in an airplane; and Figure 6 is a side elevational view thereof partially in section.

Figure '7 is a side elevational view partially in section of the structure of my invention as embodied in a water craft.

Figure 8 is a side elevational view of the structure as embodied in a land vehicle; and

Figure 9 is a vertical sectional view of the structure as embodied in a free balloon.

Referring now to the drawings wherein like characters indicate like parts I have illustrated the selected embodiment of the structure of my invention in Figures 1 through 4 as comprising a dirigible, lighter than aircraft having an outer inflatable body 2 of rubber or other suitable material formed with a rear constricted neck 4 and a rear orifice 6 and rim 1.

Conventional stabilizers 8 and rudders ID are employed exterior of the body 2, and a cab 12 is secured below the body to which air under pressure passes through the openings l3.

The nose M of the body 2 is fashioned with an exterior nozzle l5 and positioned within the body 2, I utilize an inner inflatable body or bag l6 having a constricted neck l8 lying within the neck l of the outer body and these necks are vulcanized or otherwise secured in air tight relation as at 29. The end of the inner neck overlaps the rim '6 of the outer neck as at 22, and a flexible member or connection as string 24 connects the forward ends or noses of the inner and outer bodies.

Normally the outer body 2 will be inflated to a predtermined degree through the nozzle l5 after which the nozzle is secured by a string or a rubber band or similar article, so as to maintain a closed outer body. Thus the pressure of the outer body will remain constant, giving the desired shape to the toy, until it is desired to deflate the body by removing the string S.

A person then desiring to effect flight of the toy will inflate the inner body through the orifice 6, the inner body stretching the body and further compressing the air within the outer body 2. When the toy is released, the pressure of the air between the bodies and the normal tendency of the inner body to contract, will exhaust air from the rear orifice in a jet, thereby forcing the toy forward. When the inner body is deflated, the jet exhaust will cease, but forward gliding of the toy will continue, due to the inertia of the inflated outer body.

In Figures 5 and 6, I have illustrated the structure of my invention as embodied in an airplane having wings 26 and motors 28, the structure of which is otherwise similar to the dirigible described above.

In Figure 7, I have shown the manner of construction of the toy of my invention when applied to a water craft. Ballast 30 is desirable to maintain the craft in proper position in and upon the water, and the extension 32 for the exhaust orifice is provided to effect an under water jet exhaust.

Figure 8 shows a further embodiment of the structure in a land vehicle having wheels 34 in addition to the elements above described; and in Figure 9, the structure is illustrated as embodied in a free balloon from which I suspend the basket 36 supported by lines 38.

The toy of my invention is inexpensive to manufacture and when elastic bodies of substantial material are used, will be durable. The placing in motion of the toys by releasin the same after inflation will aflord amusement and certain skills may be developed to control the flight or movement of the craft in the air currents prevailing at the time.

The toys may be used repeatedly by simply inflating the inner body and releasing, then retrieving the toy from the point to Which it has glided or coasted, and continuing. When play has ceased, the string is removed for the stor age of the toy and it is in this condition that the toys are shipped for the sale thereof.

It is believed that from the foregoing description, the operation and construction of the invention will be apparent to those skilled in the art.

Having thus fully described my invention, what- I claim as new and desire to secure by Letters Patent is:

1. In a toy, an outer inflatable body having the configuration of a vehicle and provided with a rear orifice, said body having a constricted neck and an annular rim adjacent said orifice, there being a nozzle in the front end of said body for inflating said body, an inflatable bag arranged within said body, said bag having a restricted neck arranged Within the constricted neck of said body, the restricted end of said bag overlapping the rim of said body and secured thereto, and a flexible member connecting the front end of said bag-to the frontend of said body.

2. In a toy, an outer inflatable body having .4 the external configuration of a dirigible and provided with a rear orifice, said body having a constricted neck and an annular rim adjacent said orifice, a cab dependingly carried by said body, there being openings in said body for the passage therethrough of air into said cab, there being a nozzle in the front end of said body for inflating said body, an inflatable bag arranged Within said body, said bag having a restricted neck arranged within the constricted neck of said body, the rear end of said bag overlapping the rim of said body and secured thereto, and a flexible member connecting the front end of said bag to the front end of said body.
